Abstract

Sampling of two dimensional signals is a rarely discussed aspect of signal processing. The scientific community has become used to the idea of rectangular sampling to the point that other possibilities are generally not even considered. The popularity of rectangular approach arises mostly due to its ease in extending it to three dimensions and also from a data handling point of view. In this paper, other sampling possibilities will be explored. This paper compares the qualitative and computational advantages of other approaches towards sampling of two dimensional signals. It is shown that in several cases hexagonal sampling is much more efficient than rectangular approach.
